Glossary of Art Terms

Acid freePapers with a 7 pH, or very close to 7 pH. Below 6.5 pH or above 8.5 pH is not considered acid-free. Acid free materials are more permanent, less likely to discolor, or to deteriorate materials they are placed with over time. Works on paper, and the mats, mounts, etc. with which they are framed, are best acid free.

AfterWhen used in an artist’s inscription, it means that that artwork was modeled on the work of another artist. It may either be nearly identical to the other’s work, or differ to some degree from it.

AgingThe continuous action of atmospheric components like oxygen, moisture, light, temperature – on materials and structures, leading to deterioration.

AnnotationInformation added to an image, such as arrows, pointers, words, notes for special editions (e.a., h.c.), etc.

Applied ArtsThe arts concerned with making objects with functional purposes, but for which aesthetic concerns are significant. The applied arts may include architecture, interior design, the design of manufactured items, ceramics, metalwork, jewelry, textile, glass, furniture, graphics, clocks and watches, toys, leather, arms and armor, musical instruments, etc. Commercial art may be considered a branch of applied art. The applied arts are usually contrasted with the fine arts (drawing, painting, sculpture, fine printmaking, etc.), which are seen as serving no purpose other than providing an aesthetic experience.

AppraisalA type of analysis and evaluation, especially in an official or professional capacity. In appraising works of art, for instance, an art appraiser studies their various qualities, and ultimately estimates their monetary worth, typically for insurance or taxation reasons, or in establishing a price.
